Application filed March 14., 1812. Serial No. 683,795.

To all whom it may concern:

Beit known that I, JAMns W. CONNELLY, a citizen of the United States, residing at Methuemin the countyof Essex and State of Wassachusetts, have inventedcertain new and useful Improvements in Yarn-Goilers;

and I do declare the following to be a full,

clear, and exact description of the invention, such as will enable others skilled in the art to which it appertains to make and use the same. 7

This invention relates to improvements in yarn coiling apparatus.

One object of the invention is to provide coiling attachment for yarn splitting'machines and the like, having an improved operating mechanism whereby the yarn will be coiled in a close and compact pile which will not collapse or readily fall over.

Another object is to provide a simple and comparatively inexpensive attachment of this character which may be readily connected with and operated by a moving part of a yarn-splitting machine or with anyother machine in which a coiler is required or may be employed.

With these and other objects in view, the invention consists of certain. novel features of construction, and the combination and arrangement of, parts as will be more fully described and claimed.

1n the accompanying drawings; Figure 1 is a side view of a yarn splitter showing my coiling attachment applied thereto; Fig. 2 is a rear View of the upper portion of the same; Fi 8 is a plan view partly in section of the coiling attachment showing in dotted lines the formation of the piles of the yarn; Fig. 4 is a large side view partly in section of the driving gears of the apparatus. Fig. 5 is a horizontal sectional view taken on the line 55 of Fig. l. Fig. 6 is a detail sectional view through a portion of the apparatus showing more clearly the construction and arrangement of the yarn guiding funnels. Fig. 7 is a detail vertical sectional view through one of the cross bars of the frame and the arm or bracket for supporting the pot-eyes; Fig. Sis a view similar to Fig. at showing a modified construction and arrangement of the driving gears. Fig. 9 is a: diagram showing the path followed by one of the pot-eyes employed in theform shown in Figs. 1;to 7, through which the yarn is fed to the pile to be formed. Fig. 10 is a diagram showing the path followed byone of the pot-eyes operated by the form shown in Fi g. 8 and through which the yarn is fed to the pile to be formed.

Referring more particularly to the drawings, 1 denotes the frame of a yarn splitting machine which may be of the usual or any preferred construction and in which is revolubly mounted the usual yarn carrying rolls 2. Secured to a suitable part of the frame 1 adjacent to the ends of the front roll 2 are brackets 3 in which are secured the upper ends of gear supporting shafts 4 which depend or project downwardly from the brackets and have their lower ends reduced and provided with spur gear pinions 5, said pinions being preferably cut or formed integral with said reduced ends of the shafts.

llevolubly mounted on the shafts 4 are operating sleeves 6 on which at a suitable distance below the brackets 3 are secured bevel gears 7. The teeth of the gear on one side of the splitting machine face upwardly, while the teeth on the gear at the opposite side of the machine face downwardly. Keyed to the ends of the shaft of the front roll 2 of the machine are bevel gear pinions 8 which engage the gears 7, said gears and the sleeves 6 being thus driven by the front roll 2 of the machine. Secured to the lower ends of the sleeves 6 are horizontally projecting gear supporting arms 9, said arms having on their inner ends collars 10 which are secured to the sleeves 6 by set screws or.

other suitable fastening means and on the lower ends of the shafts 4 immediately below the collars 10 are riveted or otherwise rigidly secured collars 11; In the arms 9 are arranged apertures 12 in which are secured stud shafts 13 the lower ends of which project a suitable distance below the arms 9 and have thereon gear supporting heads l l. Revolubly mounted on the stud shafts 13 are spur gears 15 which are engaged with and revolved by the stationary pinions 5 on the lower end of the shafts 4, assaid gears are carried around the pinions by the movement of the arms 9 and the sleeves 6 which are revolved on the shafts 4: by the gears 7 and 8 as hereinafter described.

In thegears 15 supported by the arms 9 at the opposite sides of the machine areformed radially disposed slots 16 in which are secured the upper ends of depending frame supporting studs 17 which are engaged with plugs 18 secured in the inner ends of the tubular side bars 19 of a yarn guiding and coiling frame 20. The side bars 19 of the frame are connected by cross bars 21 which a 1 to freely swing when operated by the gears hereinbefore described. On the cross bars of the coiling frame are adjustably secured short arms or brackets 23 in the outer ends of which are arranged pot-eyes 24: through which the yarn passes from the rollers 2 and is coiled on the floor or other surface provided to receive the piles of yarn coiled byvthe attachment. .By thus constructing and arranging the coiling frame and the operating mechanism thereof it will be seen that as the sleeve 6 and arm 9 are revolved around the shaft i, a wide rotary or circular movement is imparted to the frame while the engagement of the gear 15 with the stationary pinion 5 will simultaneously impart a quick short circular movement to the frame. By thus moving the frame it will be seen that the wrist pins 17 and poteyes 24 will follow the path shown in Fig. 9 forming spirals arranged one within the other and that the yarn passing through the pot-eyes will be wound in large and small coils or spirals on the piles disposed from four to six feet below the pot-eyes and the same amount of yarn being fed during the formation of the small coils as the large ones the yarn under the influence of the atmosphere will fall into curls or waves zigzagging from one side to the other thus building'the pipe up solidly or without a central opening, thereby obviating the possibility of the pile collapsing or falling in wardly. By adjusting the studs 17 in the slots 16 of the gears the strokes of the frame may be regulated to make larger or smaller coils of the yarn on the pile. Hence the solid formation of the piles will be obvious when it is understood that there is the same quantity of yarn in the smallest coils as in the largest and that all the coils large or small are made in the same time; that is,

the small coils are not made any quicker than the large ones. Consequently when the coils are near the outside of the pile they take up all of the yarn fed and as they grow smaller the yarn falls loosely and zigzag from one side to the other of the pile. l/Vhen the pot-eyes are traveling in small circles directly over the centers of the piles they have very little control over the yarn and hence it fallsin the very centers or around the centers of the; piles. When a pot-eye is traveling in a small circle it cannot swing thev yarn in an exact circle when it reaches the pile several feet below and consequently the falling yarn vacillates and falls in folds over the entire center of the ".pile. This condition when the pot-eye loses control over the yarn lasts for about. two

turns. Owing to the fact that the machine is run very rapidly and that the pot-eyes are about six-feet from the floor the speed of the machine will cause the yarn during its swinging or coiling motion to reach the outside boundary of the pile a turn or two before the pot-eyes make their largest circle and the yarn runs on this outside boundary until the pot-eyes return to about the same place and this givesthe right amount of yarn to the outside to render the pile even and distribute yarn quickly over its upper face. a

The size of the piles and the number of coils may vary by varying the teeth of the gear 15 and the cog wheel 5 the diagram shown in Fig. 9 being made by a machine in which the cog wheel 5 has eight teeth and the gear wheel '15 has sixty-four teeth and i when this number of teeth are employed eight circles will be formed during one revolution of the wrist pin 17 and consequently said wrist pin will travel in the same path during each revolution of gear 1 15 but as pointed out above the number of teeth in both the gear wheel and cog wheel vmay be varied but the samegeneral path will be followed. v I

From the above it will be obvious that the yarn when it reaches the pile several feet below the pot-eye through which it is fed does not assume the same path formed by the pot-eye'as the action of the air on the yarn from the time it leavesthe pot-eye. until it reaches the pile several feet be-v low causes the circles of yarn to constantly sway from one side to the other and this together with the quantity of yarn fed during the formation of the small circles,- produces a solid pile without any central opening.

When the device'shown in Fig. 8 is em ployed, it is desirable to have a small central opening in the pile for the reason that the 1.11

end of the shaft l has fixed thereon a gear 25 which corresponds to the gear 15 on'the arm 9 in the first form of the invention and which is engaged with a pinion'26 revolubly mounted on a stud shaft'27 in the arm 9 and which corresponds to. the pinion on the shaft 4 of the first form of the device. By thus reversing the gears and fixedly mounting the large gear 25, the smaller gear or pinion 26 will be revolved around the larger gear and will be turned by its engagement with saidlarger gear as will be readily understood. The pinion 26 is supported on the shaft 27 by a nut 28 and said pinion is provided on its lower end with an extension to which is secured a downwardly curved crank arm 29, the outer end of which is pivotally connected by a stud 30 to the adjacent end of the yarn coiling frame as shown. By this arrangement of the gears andframe supporting mechanism, it will be seen that a slightly different form and arrangement of coils are made by the frame, the engagement of the pinion-26 with the gear 25 causing the frame to make a series of small elliptical shaped coils, said small coils being arranged around in a circle to form the large coils of the pile, or in other words, each large coil of the pile will be formed by a series of smaller coils arranged in the large coil.

It has sometimes been found that in making large piles the yarn will not feed properly through the pot-eyes as when the frame is swung outwardly so far, the yarn is apt to fallover the eyes and in order to avoid this difiiculty, 1 preferably provide a yarn feeding funnel 31 which is suitably arranged and supported in the frame and through which the yarn passes. The upper edge of the funnel is provided with a binding or rim 32 of leather or similar material by means of which the upper end of the funnel is supported in a board 33 arranged above the coiler rods or bars of the frame in which the lower end of the funnel is secured as shown. v

From the foregoing description taken in connection with the accompanying drawings, the co-nstructionand arrangementof the invention will be readily understood without requiring a more extended explanation.
